HI so my Saturn SL1 was having issues with going up hill and losing power. I changed the spark plugs and spark wires so it is much better. It is not as bad as it was and feels like she has a lot more power now after replacing those things.

Still every once in awhile when I am going up hill, she jerks a little like she wants to lose power but then she grabs power again. Could this be fuel pump related?

Also now after changing those things when I am in idling she kinda shakes like she has more power than she is used to having. What could that be?

Thank you
